Portable insulation resistance meter CCT-5

The CTT-5 will test the Current Transformer Ratio, Phase Shift, Polarity, Excitation, Saturation, Winding Resistance and Insulation Resistance using the voltage method in compliance with ANSI/IEEE C57.13.1 & IEC 60044-1 standards, where voltage is applied to the secondary X terminals of the current transformer. The CTT-5 burden test injects a current into the secondary loop to verify the integrity of the current circuit and to determine its impedance and VA. This information is required to insure the CT will perform under all circumstances. Design Features • High resolution color display allows operator to create and save repeatable test plans • All tests are performed in automatic sequence without the need for operator intervention • Rugged design to meet the most demanding field testing environments • Large internal memory (200 testing files where each can have of up to 10 excitation curves and 140 test plans files) • All CT nameplate and equipment details are stored with the test result file • Built-in thermal printer • Full QWERTY keyboard for easy on-site data entry • 2000 VAC saturation test voltage with knee point voltage markers (ANSI 10/50, IEC 60044, IEEE 30 and IEEE 45) • Fast full testing operation. Manual mode is available for trouble shooting and special diagnostic testing. • Burden mode makes it possible to analyze the secondary circuit connected to the CT • Easy setup of test plans are created on the instrument • Convenient integrated test leads storage compartment • Automatic test report creation • User selectable time duration for insulation resistance test (10 to 60 seconds) • Automatic demagnetization sequence
